Assessment & Plan:
# UNSPECIFIED DISORDER OF MUSCLE LIGAMENT AND FASCIA (728.9):likey ligament tear assoc w/ sprain of foot/ankle left foot;improving and suspect as the swelling is resolving internally his pain is less;

Instructions printed and provided to patient:
1):agree w/ US but not avail here until 3 days from now
I will talk w/ radiology and assess if CT w/ contrast will suffice to determine vascular disruption w/ compression(pt is on coumadin): vs vascular compromise due to swelling/inflammation
